ST. LOUIS (AP) -- Ozzie Smith tied the score in the 7th inning and won the game with a bases-loaded sacrifice fly in the 11th as St. Louis beat Atlanta.

St. Louis has won four games in its final time at bat and has rallied to win in half its 12 victories. The Cardinals trailed by 3-0 before tying the score in the seventh on Smith's two-run infield single.

Geronimo Pena drew a one-out walk in the 11th off Doug Sisk (2-1) and stole second. Milt Thompson was intentionally walked and Bernard Gilkey got an infield hit when shortstop Jeff Blauser couldn't get the ball out of his glove in time for a forceout. Smith followed with a drive to center that easily scored Pena.

Sam Horn hit a home run for the Orioles, who have lost eight of 11.

KANSAS CITY, Mo. (AP) -- Emergency starter Steve Searcy combined with Paul Gibson to shut down Kansas City. Alan Trammell hit two run-scoring singles and Mickey Tettleton hit his second home run of the season in the eighth.

Searcy (1-1), who failed to get out of the second inning in his previous start, pitched five and one-third innings in place of Dan Petry, who was scratched with lower back pain.

Gibson relieved Searcy with one out and two on in the sixth, loaded the bases with an intentional walk and then threw called third strikes past Kurt Stillwell and Gary Thurman. Gibson finished with two-hit relief for his first save.

Bret Saberhagen (1-3) has had only one run scored for him while he was in the game in his last three starts. Saberhagen allowed seven hits in seven innings and struck out five before Steve Crawford relieved.
